TOOL FOR BRICKMASONS,

Specification of Letters Patent.

Patented June 3,1920.

Application filed February 17, 1919. Serial No. 277,617.

of a wall, and one object is to provide a.

tool of this character having interchangeable striker elements'to fit joints of different widths and adjustable to strike or rake out the mortar in saidjoints to different depths. A further object is to provlde a tool of this character with interchangeable troweling elements to fit into the different size joints, smooth the surface of the mortar and clean out all-loose mortar in said oints.

Other objects will hereinafter appear, and in order that the invention may be fully understood, reference will now be made to the accompanying drawings in which:

Figure 1 is a side elevation of the tool partly broken away to show a pocket therein.

Fig. 2 is a plan view of the tool.

Fig. 3 is an inverted plan view of the tool.

Fig. 4 is an inverted detail perspective view of a troweling element constituting a part of the invention.

Fig. 5 is a detail of a pin employed in adjusting the striker elements longitudinally.

In carrying out the invention, I employ a handle 1 provided at one end with an angular extension 2 and at its upper side with a recess 4 having an internally threaded plate 6 firmly secured to the bottom of the recess by suitable means, such as screws 8. The upper side of the handle 1 is also provided with wear-plates 10 removably held in place by suitable means, such as screws 12, so that said. plates can be replaced by others when worn out.

The underside of the handle 1 is provided with a pocket 14 to hold the detachable parts of the tool as will hereinafter appear. Said I pocket 14 is normally closed by a slidable cover 16 having dove-tail ends 18 to fit into corresponding grooves 21 in the handle .1. As disclosed, by Fig. 3,-the cover 16 tapers toward its rear side, so that it cannot be pushed clear through the dove-tail grooves, but must be inserted andremoved from the front side thereof. A. turn button 20 is pivoted to the handle 1 to normally hold the cover 16 from sliding out between the dovetail grooves 21.

22 designates a striker'element which is threaded into the plate 6 and locked therein from accidental displacement by a jam-nut 24. The outer end of'the striker element 22 has a conical head 26 tofit' into the joints between the. bricks and strike or rake'out the mortarto any desired depth, such depth being determined by the distance to which the upper surface of'the head 26 projects beyond the upper surface of the wear-plate 10. The striker element 22 is adjusted in or'out as desired by insertingthe pin 28 in the transverse hole 5O in the head 26 for the purpose .of screwing .the. striker element 22 inwardly or outwardly as required. Any number of interchangeable striker elements may be employed with heads of different diameters to fit .into different sized joints.

bricks are laid with wider joints, inter v changeable troweling elements of different widths as 38 are employed to fit such wider joints. Said troweling element 38 has a long marginal flange37 and a short marginal flange 39, which fit snugly over the corresponding surfaces 34 and 36, respectively, of the troweling element 32. The troweling element 38 also has spacing lugs 40 and 42, to bear against the adjacent side of the angular extension 2 to hold the edge 44 of the flanges 37 and 39 flush with the edge 46 of the trowelingelement 32. The lug 40 has a hole therein for the passage of a bolt 54 provided. with a thumb nut 56 which coacts with the bolt in holding the troweling element 38 firmly in position on the troweling element 32. The long surfaces of the troweling elements are used in smoothing the mortar in the horizontal joints between the bricks while the short surfaces are used in vertical joints between the bricks. The point 35 at the juncture of the long and short troweling surfaces 34 and 36, respec tively, can be employed to advantage in cleaning out surplus mortar in the corners of joints. 7

The depths to which the troweling elements enter the joints is regulated by a gage 48 which has surfaces 50 and 52 paralleling the troweling surfaces 34 and 36, respectively. Said gage 48 is held inplace by suitable means such as the bolt 54 and. the

thumb nut 56, said bolt 54 passing through a slot 58 in the gage, so that the same may be adjusted toward or away from the troweling surfaces according to the depth to which they are to enter the joints between the bricks. A washer 60 is interposed between the head of the bolt 54 and the adjacent side of the angular extension 2 to protect the latter from wear by' the former.

When the device is not in use the pin 28 and the interchangeable striker elements are carried in the pocket 14 so that they will always be at hand when needed. 7

From the foregoing description, it is apparent that we have produced a simple, inexpensive and eflicient tool well adapted for the purposes intended, and while we have shown and described the preferred form of our invention, we reserve the right to make such changes in the construction, combination and arrangement of parts, as properly fall within the spirit and scope of the claims. 7

Having thus described our invention, what We claim and desire t Patent, is:

1. A tool of the character described consisting of a handle provided at one end with an'angular extension,'an element on said extension provided with long and short troweling surfaces meeting in an acute angle, and a gage secured to one side of the secure by Letters angular extension and provided with long and short surfaces paralleling the corresponding surfaces of said element.

2. A tool of the character described consi sting of a handle provided at one end with an angular extension, an element on said extension provided with long and short troweling surfaces meeting in an acute angle, a gage adjustably mounted atone side,

of the angular extension and provided with long and short surfaces paralleling the corresponding surfaces of said element, and means to secure said gage at any point of its adjustment.

3. A tool of the character described con-" sisting of a handle provided at one end with an angular extension, an element fixed on said extension and provided with long and short troweling surfaces, a second element having long and short trowelingflanges to fit over the corresponding surfaces of the first element, spacing means on one side of the second element to abut the adjacent side of the angular extension, a gage tofit against one side of the second element, and means to secure said gage and the second element in place. 7 r

In testimony whereof we afiix' our signatures in the presence of two witnesses.
